Front panel buttons do not work

Capacitive Sensor buttons do not work

Manual installation of Windows operating system

Cause

The front panel of the Elite 8300 AiO and Pro 6300 AiO contains a group of capacitive sensor (aka "capsense") buttons that allow the modifaction of settings such as Volume, Mute, and Brightness. These buttons are controlled via PS/2 scan codes. Unless a PS/2 keyboard or mouse is attached prior to Windows loading, these buttons will not function without the inclusion of a certain registry key. This key is included in the HP factory image. However, a manual installation of the OS may not include this key.

The following image shows the location of these capsense buttons:

Answer/Solution

Download and install SoftPaq 60481. This SoftPaq will add the registry key which enables support for hot-plugging PS/2 devices (such as the capsense buttons).

note:

As of the creation of this article, the SoftPaq's Release Notes imply support for Windows 8 only. However, this SoftPaq has also successfully resolved this issue in Windows 7.
